Electroplankton Marine-Crystals

These plankton look like snow crystals. They make sounds when you
touch them. Move them around and stir them up.Resembling
delicate snow crystals, Marine-Crystal plankton elegantly float on the
surface of the water. The plankton get their name from their distinctive
snowflake shape. They grow in clusters of 35 and line up in very orderly
formations. When stimulated, Marine-Crystal plankton spin and produce
vibrant sounds. While the plankton do grow in size if they are
repeatedly tapped, they gradually return to their original size over
time. They are born in four polygonal shapes: triangle, square,
pentagon, and hexagon. The ends of the crystalline protrusions also take
on the same shapes. The tone of the sound they make changes depending on
the shape of the Marine-Crystal plankton’s body.
